Every batch we sell is tested by an independent lab for identity and purity. Find the report for your vial: search the product name or the batch number printed on the label.
Each Certificate of Analysis documents the identity and purity (99%+ by HPLC) of one production batch, issued by an independent laboratory. A printed copy ships with every order, so you can match the batch number on your vial to the report above. Missing a batch? See the FAQ or email us and we will send it directly.
All products are supplied strictly for in-vitro laboratory research use only.
